Only reason I ever hacked my gear was because of how RNG (short term for something that is completely randomized) dependent the rolling system was. If i'm going to play ranked for say, 2 hours, and hypothetically gain up to 100-200k in gold and use all of it to roll my gear to get the stuff i want and still never get it, then yeah im going to stop wasting my time grinding cash just to waste 90% of it.
I can understand the gripes with "hacking" because that word alone eludes to the fact that you would be cheating and that would constitute as an unfair advantage. however, the difference between hacking your gear so that all of it is perfect roles and actually legitimately cheating by manipulating matches is completely different. you can roll a perfect set of gear naturally and it would be no different from the gear you hack. Now if there was some gear hacking application that did get developed for splatoon 2, i'm not gonna lie I would probably use it. but the thing with this game is that there is less of a a need for it because of how balanced they made the system overall. Splathax was created because the system wasnt balanced. so i doubt there will be a need to do all of that again this time around.
